The British couple, now based in Los Angeles, were all over the news last summer, when photos were leaked of Sanders cheating on Ross with Kristen Stewart, whom he directed -- along with his wife -- in Snow White and the Huntsman. The affair was acknowledged, and apologies made; Stewart and boyfriend Robert Pattinson appear to have reconciled.

According to TMZ, Ross is asking for joint custody of her two children with Sanders, aged five and seven; and Sanders, in his response, seeks the same, and is not asking for spousal support.
